Before You StartYour OfficeConnect hub comes with:
■ One power adapter for use with the OfficeConnect hub.
■ A Product Registration card for you to fill out and return.
■ Four rubber feet.
■ A stacking clip.
■ Two unit labels and eight cable ties.
■ An OfficeConnect Network Assistant CD-ROM.
The extra parts mentioned in the next section are not supplied with the hub.
Workstation Connections
To connect workstations or other equipment to your hub, you need:
1 One 10BASE-T, 10/100BASE-TX, or 100BASE-TX adapter card for each workstation. 3Com produce a range of easy-to-install network adapters, which provide your workstation with a suitable connection.
2 An operating system (for example, Netware or Windows 95/98) with network support configured, running on your workstations.

Stacking the Units Together
The Rubber Feet
The four self-adhesive rubber feet prevent your hub from moving around on your desk. Only stick the feet to the marked areas at each corner of the underside of your hub if you intend to place the unit directly on top of the desk. Do not fix the feet if you are going to use the clip.
The Stacking Clip
The blue stacking clip allows you to stack your OfficeConnect units together neatly and securely.
CAUTION: You can stack up to a maximum of four units. Smaller units must be stacked above larger units.
To fit the clip:
1 Place your unit on a flat surface.
2 Fit the clip across the top of the unit, as shown in Figure 2 (picture 1), ensuring that the longer sections of the fastening pieces are pointing downwards.
3 Align the fastening pieces over the slots found on each side of the unit.
4 Push the clip down gently to secure it, ensuring the fastening pieces snap into the slots on the unit.

Positioning Your HubWhen installing your OfficeConnect hub, ensure:
■ It is out of direct sunlight and away from sources of heat.
■ Cabling is away from power lines, fluorescent lighting fixtures, and sources of electrical noise such as radios, transmitters and broadband amplifiers.
■ Water or moisture cannot enter the case of the unit.
■ Air flow around the unit and through the vents in the side of the case is not restricted. We recommend you provide a minimum of 25.4 mm (1in.) clearance.

Connecting Workstations and Other Equipment to Your Hub
WARNING: Please read the ‘Important Safety Information’ section before you start.
WARNHINWEIS: Bitte lesen Sie den Abschnitt ‘Wichtige Sicherheitsinformationen’ sorgfältig durch, bevor Sie das Gerät einschalten.
AVERTISSEMENT: Veuillez lire attentivement la section “Consignes importantes de sécurité” avant de mettre en route.
CAUTION: The equipment connected to the Hub must be set to operate in auto-negotiate or half duplex mode.
Connecting workstations and other equipment to your Hub is easy. To connect a workstation to any of the Hub’s ports, use a ‘straight-through’ TP cable. Refer to “Twisted Pair (TP) Cables” on page 8 for further information.
If you are using port 16 to connect a workstation, ensure the Uplink/Normal switch is set to Normal (out).
TP cables are very easy to use. To connect a cable, simply slot the connector into the appropriate RJ-45 port. When the connector is fully in, its latch locks it in place. To

3Com recommends that the cable (B) between the Fast Ethernet hubs is no longer than 5m (16.4ft). This allows the maximum hub-to-workstation cable length (A or C) of 100m (328ft) to be used, as shown in Figure 3.

Making the Connection to Another Hub
You can connect a 10BASE-T, 100BASE-TX, or another 10/100BASE-TX OfficeConnect hub to any port on the Dual Speed Hub 16. Use the following method:
1 Using a straight-through cable, connect the Uplink/Normal port of the Dual Speed Hub 16 to any of the ports on the other hub (as shown in Figure 5). If using an Uplink/Normal port on the other hub, set its Uplink/Normal switch to Normal (out).
2 Set the Uplink/Normal switch for the Uplink/Normal port on the Dual Speed Hub 16 to Uplink (in).
Checking Hub Connections
When you have connected all the appropriate workstations and other equipment to the Hub, power on the Hub. For each port with a connection, a Port Status LED should be on. If the port is operating at 100Mbps, the corresponding LED in the upper row of Port Status LEDs is on. If the port is operating at 10Mpbs, the corresponding LED in the lower row is on. If neither LED is on, check your connections.
Spot Checks
At frequent intervals, visually check that:
■ The Alert LED is off — this is the best way to find out if there are problems with your network.
■ Case vents are not obstructed.
■ Cabling is secure and not pulled taut.
